“One of Williams Advanced Engineering projects is the design and manufacture of the batteries for the FIA Formula E Championship.”


Doug Campling, Williams Advanced Engineering’s motorsport to FormulaE.com :

“Williams Advanced Engineering is the technology and engineering services business of the Williams Group. “

“There were a couple of directions we could go with more liquid cooling or more air cooling. Obviously each driver has two cars, but we needed to consider the scenario whereby if you had an issue with one car – a repairable issue – you might need to use one car and then use it again straight away. To charge the battery in 45 minutes or an hour and simultaneously cool the battery down, ready to be used again meant that we had to have a pretty effective post-conditioning system. Liquid cooling provided the best solution”





In the end, Williams Advanced Engineering believes that racing improves the breed and we should expect higher energy density batteries thanks to Formula E. However, since the series is limited toSpark-Renault SRT_01E cars for two seasons, we don’t expect to see progress until late 2016 when the third season begins with different cars from teams.

How hard is it to make sure that the Lithium battery does not suffer from major overheating during a race? #AskAmlinAguri
The Williams battery is very well protected against over heating in the race. We have not had a problem yet, nor have we come close to having a problem with the batteries in this respect. We have a large radiator in the right hand side-pod on the car specifically designed to keep the battery safely within it’s operating range at all times during the race.

One safety feature is that the car will automatically be de-rated on power if the battery exceeds a specified temperature limit.

And then some Tesla.

Will Tesla need a solution with bigger cooling pumps,radiator fans and radiator in the future?

It is actually a family car, and not a racing car or what?


After what I understand the RWD have three cooling pumps and 4WD have five.
